T0. all whom t may concern `Be it known that we, RorvR. IRELAND, and

ALERrF. F. GiLsoN, citizens. ofthe United States, residing at Chicago, in the countyof Cook and State oflllinois, and at Closter, in the county of Bergen and State of New Jersey, respectively, have invented a certain new and useulmproveinent in House Tele-V phone Sets, of which thefollowing is a full, i0k

clear, concise, andexact description.

intercommunicating systems,

Y ,Itis an object of this inventionto provide acompact, inexpensive f substation set which may be installed in an ordinary outlet or junction box such as is commonly used inhouse wiring systems for the receptionof.

lighting switches.' With this object in view, a signaling`device such as a bellA or buzzer,

a push button switch for signaling other substations and a spring jackV forconnecting a hand ltelephone set to the telephone line,`are mounted upon a suporting plate which is adapted to be secure to the junc-V tion box. "A brass cover or wall plate, which is similar to the wall platesy used in connnec tion with lighting systems, acts'as-a cover for the outlet box and in conjunction with the outlet box entirely inclosesthe substation apparatus. A suitable-aperture is,provided inthe wall plate. throughjwhich the42k push button may project, and another aper-v V ture through which connection may be made Y to the spring jack.

, The invention will be v'more fully under-V stood by referring to the accompanying drawing -wherein- F igurerl .is a rearperspectiveiview'ofthe apparatus with a port'ion'of the outlet `box broken, away to show the mounting ofythe .n signaling device and other substation apparatus.

Y i Y Y' i ln the drawing, 1 'indicates the outlet or junction. box which niay be and preferably is in allfrespectssimilar to the usual box of this type'which is used `inhouse wiring systemsforthe reception of switches,etc.y This box is'- adapted to be installed iny ka recess in the wall `of aroom with its outer end flush necting with 'the conduit, commonly used in house wiring. The outlet box 1 is provided with twoV ears V3 to y.which the supporting plate et may be attached by means 'of screws 5.VV The lsupporting plate 4f, as shown in Figs. l and 3, isvprovided with two lugs 6 object of such VVslots being to allow adjustoutlet box.

Mounted substantially centrally on the in- Sula-ting plate'8 and'extendingfat right angles thereto isa fbracketfpiec'e 18. This bracket is provided Vwith Vanangularly disposed end 19 `through Whichfa V:plurality of eyelets are passed to secure the bracket to the insulating plate.

Adapted to Viit over the supporting plate-v L.lc-'and toclose the open end ofthe junction for outlet box, is aivvall `or'cover -plate 20.

Thiswall plate is provided with two apertures,-one ofl'whiclrregisters vvith` the push button aperture@ ofthesupporting plate ,4, and the other registers with the jack f sleeve Vaperture 10.

As is lshown' in Fig. 2, the Wall plate adi jacent'vthefjack sleeve l2 isprovided with an -annularfdepression 21; The screws 22l andr 23 serve-to-secure thevvalliplateto the supporting plate-1 land hence tofthe outlet or'junction box `1". The screvv 23, in addition to securingthe Wall plate 5 to the sup-- yporting plate, also` provides one point of attachment fo'r1h0'ok24. The hook 24e is. providedwvithfan yupper annular end 25,y

preventing the hook `:trein turning about the kscrew 28. Thefhook 24 provides aineans of Fsupport for the lordinary, portable telephone set.

Securedto the outlet-box 1 by'screvvs 2.5,

is aplurality 'of supporting lugs 26, by

j meansof which the outlet box may bese=` f `cured Within arecess inthe Wall.

, The'substation apparatus herein described I is very compact and inexpensive and is so arranged that it maybe entirely inclosed Within an, ordinary junction orr outlet box Which may be installed at the time that the house Wiring system is installed. Because of the lfact that all of the apparatus is contained in ftheo'utlet box 'andi is covered by a Wall plate which conforms t'o 'the other electrical fixtures in the room in which it is installed, the set is very, neat in-appearance,

does vnot fprotrude Ifrom Vthe surface 'of the y'Wall and does notfdetract fromtheappearance ofthe room.
